The pinions 31 made, the head being adapted to contain preferably are pivoted to the cover 23 by a bowl 14 having any desired rotating and arbors 32 seated interchangeably in holes separating elements, milk-supplying devices 33, said holes being arranged in concentric and spouts not shown. An electric motor rows .to accommodate various diameters of 15, shown conventionally, is mounted in the pinions. The gear assembly can be modified frame and is secured to the standards 11, in relation to the diameters of the pinions 12 by supporting bands 16, 17 the armature employed, to the end of changing the gear shaft 18 of the motor being perpendicular to ratio and R. P. M. of the shaft 29 relative tothe armature shaft 18. The upper end portion of the shaft 29 is journaled in a bearing 34 in the head 13 and said shaft carries the rotatable elements of the cream separator Within the bowl 14 and not shown. An oil fount, for lubricating oil, 35 is mounted above the horizontal plane of the bearing 34 and a feed pipe 36 leads from said fount to the interior of said bearing and provides lubrication for the shaft 29 therein. An overflow pipe 37 leads from the interior of the bearing 34 to the interior of the ste'adying bearing 21 and utilizes the overflow of oil from the upper bearing to provide lubrication for the lower end of the armature shaft 18 and the step ball 19 insaid'loWer bearing. An electric condue tor 38, under control of a rheostat 39, provides current for operation of the motor.

WVe claim as our invention- In a driving mechanism, a frame and a shaft substantially centrally thereof, a motor mounted in said frame and having a. shaft substantially in alineinent with the first shaft, a gear case on said frame in which said shafts are journaled,an internal gear rotatably mountediin said case, pinions fixed to the shafts concentrically of said internal gear andr'emovahle and replaceable July, 1922,
